Question

State van't Hoff-Avogadro's law.

Answer 1

Avogadro's law states that equal volumes all gases at the same temperature and pressure have the same no of molecules.For a given mass of an ideal gas, the volume and amount(moles) of the gas are directly preportional if the temperature and pressure are constant.

Answer 2

Answer:

Avogadro's law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional provided temperature and pressure are a constant.

The law is expressed as:

                    V ∝ n  

V is the volume of the gas;

n is the amount of substance of the gas (measured in moles);

k is a constant.
